I'm sorry, but who decides what level of proficiency a poster needs to have attained before he can ask a question?
Or what make's a certain question 'valid' or not?
Just help who you want to help, in whatever way you want to help them. Or not, for that matter.
If you think someone doesn't 'deserve' a helpful reply because they haven't put in the groundwork just move on and leave it unanswered.
I'll carry on helping whoever I can, whenever I want, whatever their level. Unless they're rude. That's
my only proviso.
